.DISCUSSION...
THINKING THE LACK OF WIND VELOCITY WITHIN THE MIXING LAYER WILL KEEP
THE RH SOMEWHAT ABOVE 23 PERCENT THIS AFTERNOON...BUT UPPER 20S NOT
OUT OF THE QUESTION. OTHERWISE...A RIDGE OF HIGH PRESSURE WILL BE
CENTERED OVER THE BURN AREA...SO WINDS ARE EXPECTED TO BE CALM IN THE
MORNING AND BECOME LIGHT AND VARIABLE BY MID AFTERNOON.
